CAUTION:
For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to parts list).
indicates safety critical
components. For continued protection against risk of fire, replace only with same type and rating fuse(s). To reduce the risk of electric shock, leakage-current or
resistance measurements shall be carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer.
The DC voltage is an actual reading measured with a high impedance type voltmeter with a cassette loaded at playback mode. The measurement value may
vary depending on the measuring instruments used or on the product. Bias circuit DC voltage is measured while in the record mode.
